Registry Tip : Install PNPISA device after saying NO


You installed the PNPISA driver to give NT some Plug
and Play functionality. Then you said NO to install drivers for some device it
detects. Perhaps you are in a hurry and are going to do it at the next reboot.
Unfortunately upon detecting the device on later boots, NT will not give you the
install prompt again. To force NT to do so, delete the key entry for the device
under

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pnpisa

Delete the device’s key and NT will detect the device upon reboot and reset
the key. NT will then give you an opportunity to install its device driver.
Which key is it? You will have a key for each PNP device detected. Use the
Description value to link devices to keys.
